PRINTING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 678,449, dated July 16,1901. Application led August 2, 1893. Renewed December 6, 1900. SerialNo. 38,958. (No model.)

To all whom it may concern:

. Beit known that I, HENRY A. WISE Woon, a citizen ofthe United States,residing at New York, in the county of NewYork and State of New York,have invented a new and useful Improvement in Printing-Machines, ofwhich the following is a specification.

The aim of this invention is toimprove webprinting presses in which twoprinting-couj 1o ples are used, each couple comprising animpression-cylinder and a flat printing-form. In all theseprinting-presses, so far as I am aware, the `members of each'couplelhave always been arranged to be in impression or printing contact atthe same time and also to be out of printing contact (especially on thereversing movement) at the sametime. It is well known that it takes agreat deal of power to operate a press of this character 2o while thetwo couples are in impression or printing Contact and a great deal lesspower to operate the press while the members are not in impression andwhile the moving members are reversing. This variance causes presses ofthe character stated to run irregularly, to be subject to Violent shocksand strains, and requires that the maximum power of impression beapplied to the machine at all times. 3o My invention consists incounterbalancing or so arranging the two cylinders and two beds of aweb-printing press that while the members of one couple are inimpression the members of the other couple are not inimpression, thereversing movement taking place, and vice versa. Y

Vith this improvement the resistance of the machine at all times isbrought nearly, if not quite, to a constantthat is, the maxi- 40 mumresistance of one printing-couple is opposed to the minimum resistanceof the other couple, and vice versa, whereby an average resistance isoffered by the machine at 'all times. By this arrangement and inventionpower can be evenly applied to the machine and the saine can be run at ahigh and an even speed without the heavy jar and shock now common inthetwo-couple printing-machine.

My invention vr,is especially applicable to two-couple web-printingmachines which involve in their structure reciprocating members, such asreciprocating printing members, reciprocating impression members, orboth reciprocating printing and impression members.

y yWith my invention applied to a two-couple'printing-machine of thischaracter the counterbalanced movement of the reciproeating memberscauses the machine to re- 6o `semble in action very nearly a rotarymachine, which is the fastest machine known; but the rotary machine hasthe disadvantage of poor printing, due to the use of curved plates, suchas stereotype-plates, and therefore for fine printing flat type-plateson iiat forms must be used. Therefore if the press which usesreciprocating members which can carry flat forms can be brought inaction and resistance to resemble the rotary press the 7o reciprocatingpress can be brought to more nearly compete in speed with the rotarypress and at the same time do better work.

Y By my invention the speed of the reciprocating-member press can begreatly increased. 7 5

As before stated, the couples of a machine to which my invention isapplicable consist each of an impression member and a printing member.The printing member usually consists of abed upon which the form orprint- 8o ing-surface can be secured. The impression member usuallyconsists of an impressioncylinder which is adapted to press or presentthe material to be printed to the printingsurface. Thesebedsandcylindershavebeen variously arranged in two-couple printingmachines, 'towhich my invention is applicable.

In some presses the beds reciprocate and theoylindersarestationary.Insome presses 9o the cylinders reciprocate and the beds are stationary.In some presses both beds and cylinders reciprocate in opposition; butin all these presses in which two couples are used, as before stated,the reciprocating mem- 9 5 bers of the two couples move in unison, and

hence lthe faulty action before referred to.

My invention applied, as before described, to

any of these two-couple presses, in which either or both the members ofeach couple reroo ciprocate, will transform the resistance and actioninto nearly a constant.

My invention is therefore of this general application; and it consistsin operating or arranging a two-couple web-printin g press having bedsand cylinders so that the members of one couple are in impression orprinting contact while the members of the other couple are out ofimpression and the reversing movement taking place.

A further advantage of my invention as applied to a web-press of thischaracter lies in the fact that with my invention the web will only haveto be shifted around one impression member at a time, as the impressionis off only in one couple at a time. Hence the feed or shift of the webaround or under either one or the other of the two impression members isalways, or substantially so, taking place. This shortens the part of theweb that has to be intermittently fed or shifted, or rather divides itinto two parts, in which parts the web is alternately shifted. Thisgreatly helps the web through the press and reduces the strain on theweb and at the same time increases the speed and easy action of themachine.

In order to enable any person skilled in printing-machines to practicemy invention, I will show and describe a web-printing machine in whichthe impression members of each of the two couples consist ofreciprocating cylinders and in which the printing members of each of thetwo couples consist of stationary beds upon which the printing surfacesor forms may be placed and secured.

Referring now to the accompanying five sheets of drawings, forming partof this case, Figure lis a side elevation of a printing-press of thisespecial character with my improvements applied thereto. Fig. 2 is asection or diagram showing the parts in one position. Fig. 3 is asectional elevation showing the parts in another position. Fig. t is asectional elevation illustrating a modification hereinafter referred toat length, and Fig. 5 illustrates a still further modification of myinvention.

In the perfecting or double printing-form of this press twoimpression-cylinders are used, each impression-cylinder coacting with aseparato form-bed. In this last style of traveling-cylinder press, inwhich two traveling impression-cylinders are used, all forms of pressesheretofore devised have been arranged so that both cylinders print atthe same time and so that both cylinders are off the impression, and thefeed takes place at the same time around both cylinders. In this form ofpress it has been found that the strain all comes on the drivingmechanism when the cylinder or cylinders are in impression, but thatwhen the cylinder or cylinders are reversing olf the forms and the feedtaking place very little power is needed to perform this operation. Ofcourse by arranging the two cylinders so that they are both printing atthe same time and so that they are both oif the form-beds at the sametime the driving mechanism will at one time have to supply a heavy poweror thrust to perform the printing operation and at another time will berun easily. This is practically what limits the speed at which thismachine is run to-day.

It has been found that when the two-cylinder machine is run at a highrate of speed the action of the press is very irregular, due to theirregular resistance offered by the moving parts.

As before described, the aim of this invention is to so construct thepress that the power may be evenly absorbed by the same and to soarrange the parts that they will be very smooth-runnin g and willcounterbalance each other, one impression-cylinder printing while theother is reversing, whereby the power will be evenly divided between andabsorbed by the two reciprocating cylinders. By this means a very highrate of speed can be obtained. I also arrange the twoimpressioncylinders so that one is printing as the other cylinder is othe form-bed or reversing. The feed of the web will take place aroundthe latter, whereby the web will be properly fed and the strain thereonequalized. In connection with this I have invented and improved thefeeding mechanism, so that the feed will properly take place around eachimpressioncylinder as the same is off the impression.

' Referring now to the vdrawings and in detail, IO l0 designate the sideframes of a machine ofthe character referred to. Secured between theseside frames are the two form-beds C and D, with which coact thereciprocating impression-cylinders A and B. The impression-cylinder A ismounted in suitable reciprocating carriers E, which carriers E aremounted or gibbed to suitable guides e, secured to the frames, and thisimpression-cylinder coacts with forms placed upon the bed G. Theimpression-cylinder B is mounted in similar carriers E, which are gibbedor secured to guideways e on the frames, and this impression-cylindercoacts with forms placed on the bed D. Arranged at each side of eachimpression-cylinder in any of the usual manners are form-rollers F I",to which form-rollers ink may be supplied in any of the usual manners.The impression cylinders have gears on the ends of the same, which meshwith suitable racks arranged on the sides of the beds, as indicated indotted lines in Fig. l, so that as the impression-cylinders travelforward and backward they will revolve to properly register with theforms, which arrangement is well understood.

NV represents a web-roll from which the web is led into the machine.

From the web-roll W the web is led between the continuously-runningrollers 1l, l2, and 13, which draw the web from the roll and feed thesame into the press. From the roll 13 the web is led around thelooping-roller It, then around the stationary guide-roller l5, thenaround the guide or roller 16, mounted in the carriers E, under theimpression-cylinder A,

IOO

IIO

then around the guide-roller 17, also secured in the carriers E, aroundthe guide-roll 18, secured in the frame of the machine, around thelooping-roller 19, then around the stationary guide or roller 20. Thisstationary guideroller may be made adjustable for the purpose ofobtaining register of the web between the two impression-cylinders. Fromthe roller 20 the'web passes to the rollers 2l and 210, secured in theframe of the machine, then around the looping-roller2l1,and then aroundthe stationary guide or roller 212, then to the guide or roller 22,secured in the carriers E', around under the impression-cylinder B, thenover the guide or roller 23, also mounted in the carriers E around thestationar 0fuide or roller 24, mounted in the frames, around thelooping-roller 25, then out through the continuously-runningdelivery-rollers 26, 27, and 28. The guides 15, 18, 20,21, 210, 212, and24 are preferably made in the form of rollers, which, While stationaryin the frames, are free to revolve. By this passage of the web it willbe seen that the web will be presented to have one side printed fromforms upon the bed C and to have the other side printed or the webperfected by forms placed upon the bed D.

A suitable driving-shaft 29 is mounted in the frames, as shown, to whichpower can be applied in any suitable manner, and on the ends of thisshaft 29 are arranged pinions 30. These pinions 30 engage gears 3l,mounted on a shaft 32, journaledin the main frames. These gears 31 carrycrank-pins 33, which crank-pins 33 are connected by suitable pitmen 34to the reciprocating carriers E. Also meshing 'with the pinions 30 arethe gears 36, which are mounted on the shaft 37, journaled in the mainframes of the machine. Secured to these gears 36 are crank-pins 38,which are connected by suitable pitmen 39 to the reciprocating carriersE. This gearing is the same on each side of the press. It will be seenthat the two sets of gear-wheels 36 and 3l turn in the same direction;but it will be seen that the two sets of crank-pins 33 and 38 are setquarter-ing. By this means one impressioncylinder will be off theform-bed while the other impression-cylinder is on the form-bed.

The length of the forms is preferably so arranged that each cylinderwill be in engagement with the same for one-quarter of the revolution ofthe crank-pins-that is, each impression-cylinder will engage the formsduring two-quarters of the revolution of the crank-pins and will be offthe forms in either direction during one-quarter of the revolution ofthe crank-pins, the crank-pins thus making a complete revolution. Thesequarters will be determined, of course, by drawing forty-iive-degreelines through the centers of rotation of the two sets of crank-pins.Meshing with one of the gears 36 is a gear 40, which is one-half thesize of the same and which is mounted on the shaft 41, journaled in themain frame 10. Secured on this shaft 4l is a miter-gear 42, which mesheswith a miter-gear 43, secured on the end of a shaft 44, which is mountedin suitable bearings or journals secured to the frame 10. Arranged onthe end of this shaft 44 is a bevel-gear 45, which meshes with anddrives a bevel-pinion 46, mounted on the end of a vertical shaft 47,which is journaled in the brackets secured to the nrain frame 10.Mounted on this Vertical shaft 4.7 is a bevel-pinion 48, which mesheswith and engages a bevel-pinion 49, secured on the continuously-runningdelivery-roller 27. The continuously-running delivery-rollers 26, 27,and 28 are gea-red together, andby this means it will be seen that theywill be continuously revolved. Also se-` cured to this shaft 47 is abevel-pinion 50, which meshes with a bevel-pinion 51, secured upon thecontinuously-running roller 12. The continuously-ru-nning feeding-inrollers 11, 12, and 13 are geared together, and by this means it will beseen that they are continuously turned to feed the web into the press.Also mounted on the shaft 44 is a miter-gear 52, which meshes with andengages a mitergear 53, secured on the end of the shaft 54, Which shaft54 is j ournaled in suitable bearings or journals secured to the mainframes. Arranged on this shaft 54 are two heartshaped cams 55. Bearingagainst these heartshaped cams are rollers 56, mounted on arms 58, whicharms 58 are journaled or pivoted upon a shaft 59, secured in the mainframes. The rollers 56 are kept normally against the cams by means ofsprings 57, which are connected to the arms 58 and to the main frames,as shown. The left-hand ends of the arms 58 are connected by suitablepitmen 60 to rods or brackets 61, which rods or brackets 61 are securedin suitable bearings or ways in the main frames and which rods orbrackets 61 carry the loopingrollers 14 and 25. The other ends of thearms 58 are connected by pitmen 62 to arms or brackets 63, which aresuitably mounted in the main frames so as to be vertically movable andin which arms or brackets 63 the looping-rollers 19 and 211 are mounted.

It will be seen that by the gearing before described the cams 55 willturn twice for every revolution of the crank-pins 33 or 38, and by thismeans the feed will properly take place. It willalso be seen byreference to the diagrams that the web is loopedl in the same manneraround all the looping-rollers 14, 19, 211, and 25, but that thelooping-rollers 19 and 211 move up as the rollers 14 and 25 move down,and vice versa.

In Fig. 2 the parts are shown in the saine position as in Fig. 1. Inthis arrangement IOO IIO

the impression-cylinder B is in printing concylinder A, the web given upby the continuously-running feeding-in rollers 11, 12, and 13, and thelooping-roller 14 being taken up by the downwardly-movinglooping-rollers 19 and 211. These downwardly-moving looping-rollers 19and 211 are, in effect, a single looper, which has twice the capacity ofthe looper 14 and which acts to take up both the web supplied by thecontinuously-innning feeding-in rollers and'by the upwardly-movingfeeding-in roller 14, and of course a singie looping-roller havingdouble the movement could be used in place of the rollers 19 and 211, asshown and described in one of the modifications. The web from the roll212 to the roll 24 is held stationary and is being pressed by theimpression-cylinder B onto forms placed upon the bed D. Theloopingroller 25 is rising, and the web let out by this risinglooping-roller is continuously paid out of the press by thedelivery-rollers 26, 27 and 2S. By this means the feed around theimpression-cylinder A at its left-hand eXtreme takes place.

In Fig. 3 the crank-pins are shown as having made a quarter-revolution.This will move the impression-cylinder B to its lefthand extreme andwill draw the impressioncylinder A onto the forms placed upon the bed C.In this position of the parts the looping-rollers 14 and 25 are movingdownwardly and the looping-rollers 19 and 211 are moving upwardly. Theweb fed in by the continuously-running feeding-in rollers 11, 12, and 13is being now taken up by the downwardlymoving looping-roller 14 and theweb between the rollers 15 and 18 is held stationary, so that theimpression-cylinder A can properly act. The web let out by theupwardly-moving looping-rollers 19 and 211 is being taken up by thedownwardly-moving looping-roller 25 and the continuously-runningfeeding-out rollers 2G, 27, and 2S, and thus the feed around theimpression-cylinder B is taking place. The feed of the web around theimpression-cylinders at the right-hand extremes is just the same, theimpression-cylinders simply being in their other extreme positions, thefeeding mechanism then being, of course, in the same position asindicated in the diagrams, as the cams turn twice as fast as thecrank-pins. The action of the looping-rollers 14 and 25 in conjunctionwith the continuously feeding-in and feeding-out rollers is well known.When the looping-roller 14 moves downward, it takes up all the web fedin by the continuously-running rollers; but when the looping-roller 14moves upward both the web fed in by the continuously-running rollers 11,12, and 13 and that paid out by the roller 14 is delivered forwardaround the roll 15. Thus the web is intermittently paid out around theroll 15. As the looping feeding-out roller 25 rises it will supply justthe web necessary for the proper action of the continuously-runningfeeding-out rollers; but as the looping-roller 25 descends a doubleamount of web will be eva/44e pulled forward around the roll 24, dueboth to the downward action of the looping-roll 25 and the action of thecontinuously-running feeding-out rolls. The action of the otherlooping-rollers 19 and 211 allows the feed to properly and nicely takeplace around the impression-cylinders at the proper times and isa verysimple and eiicient mechanism for this purpose. By this means it will beseen that I have gained the great advantage of having oneimpression-cylinder printing while the other impression-cylinder is offits formbed and its feed properly and accurately taking place.

Of course the proportions of the time in which the cylinders areprinting and reversing and the shape of the cams could be varied asdesired. Also it will be seen that the loopers are arranged in the pathof the web between the impression-cylinders to perform the importantfunction of intermediate looping devices, and by their arrangement theweb will only be shifted around one impression-cylinder at a time.

My preferred form of feeding devices will be seen to becontinuously-running feedingin rollers, a looping feeding-in roller, anintermediate looping device arranged in the path of the web between thetwo impressioncylinders acting in opposition to the feedinginlooping-roller and adapted to draw forward the web as fast as the saineis paid out both by the feedingin rollers and the looping feeding-inroller and a looping-out roller arranged in the path of the web beyondthe last impression-cylinder acting in unison with the feedinglooping-in roller, and the continuously-running delivering-rollers.

While it is preferred to continuously slack the web off the web-roll andto deliver the web continuously from the press, this is not necessary sofar as the broad scope of myinvention is concerned, as the feedingdevices may be otherwise arranged.

Any equivalent device may be substituted for the looping-rollers, and Ido not Wish to be understood as limited to the feeding mechanisms I haveshown. In the device that I have previously discussed the beds are shownas arranged one directly over the other.

Of course my invention is applicable to any convenient arrangement ofbeds. Thus in Sheet 4 of the drawings I have shown the two beds C and Das arranged in the same horizontal plane and the impression-cylinders`as each driven by a separate driving mechanism, substantially the sameas the driving mechanism described and clailned in my application filedDecember 19, 1892, Serial No. 455,613. This driving mechanism consistssubstantiallyof a yoke, as J, to which the bearers H, that carry theimpression-cylinder A, are connected. Engaging this yoke .I is acrank-block K, which is mounted on a revolving disk or crank-arm L. Asimilar driving mechanism J' H K L is used in connection with the secondimpression-cylinder IOO IIO

B, and the crankpins of the two driving mechanisms are set quarteriug.To Vdrive the disks L and L', I attach bevel-gears, as 100, to the underside of the disks. Engaging the left hand of the gear 100 is thebevel-pinion 102, and engaging the right-hand bevel-gear is abevel-pinion 203. These bevel-pinions are mounted on shafts 204 and 205,respectively. Mounted on these shafts are large gears 98 and 99, whichmesh with intermediates 206 and 207, which intermediates mesh with asingle driving-gear 20S, to which driving-gear power may be suitablyapplied. The cams 55 may be driven from the gear 98, as by means of gear209 and 210, meshing with a gear 211, secured upon the cam-shaft 54, asshown. In this modication the two intermediate looping-rollers 19 and211 are mounted so as to move upwardly 'and downwardly together, and inopposition to the feeding looping-in roller 14. Otherwise thearrangement of parts in this modification is the same as that previouslydescribed, and the action of this modification is readily understoodfrom the previous description. the web through the press in thismodification is substantially the same as before described, except thata registering-roll, as 200, corresponding in function to roll 2O of theprevious device, is used between the two impression-cylinders, and thatthe web from the last impression-cylinder B passes over two intermediateguiding-rollers, as 240 and 24, to the looping-out roller 25, thelooping guiding-roller 24 corresponding in function to thelooping-roller 24 of the previous device. This press possesses theadvantages of that of the press previously described.

In the two presses previously described the web is perfected or printedupon each side.

There is another form of press in which two travelingimpression-cylinders are used, and the same is known as the two-colorpress, by which the web is twice printed upon the same side by twoimpression-cylinders. My invention is equally applicable to this styleof press, and one formof such device is shown in Fig. 5. This device isarranged substantially the same as that before described, eX- cept thatthe web passes directly from one impression cylinder to the other, andbeyond the last impression-cylinder B is led down over the stationaryroll 7 5, under a looping-roller 80, which acts in unison with thefeeding-in looping-roller 14. It has been before stated that theintermediate looping device is in effect simplya looper which acts inopposition to the feeding-in looping-roller and the feeding-outlooping-roller, but which takes up twice the amount of the web, and ithas been before stated that a single roller could be used in the path ofthe web between the impression cylinders. This is shown in thismodification. In this modiication the pivot 59 of the arms 58 isarranged so that the looping-roller 19 will have double the movement oft-he looping feeding-in roller The path of 14. A convenient way to drivethe feedingout looping-rollen is to connect the arms 81 (as by slottedjoints) to the ends of the arms 58 to pivot these arms, as at 82, andconnect the same by pitman 84 to the arms 83, which carry thelooping-roller 80. With this form of press the action is substantiallythe same as that in connect-ion with the other devices, except that theweb is twice printed upon the same side. I

In the device shown in Fig. 4 it will be seen that the feeding-outlooper is arranged oppositely to the feeding-in looper, but that the twolooping-rollers 14 and 25 move oppositely. This is in eect the same asforming the loops in the same direction and moving the rollers in thesame direction, as is shown in the device in Figs. 2 and 3. In thismodification shown in Fig. 4 the feeding-in and ,feedingoutlooping-rollers act i-n unison; but the intermediate looping devicesmove in opposition to the feeding-in and feeding-out rollers. It is notnecessary that the two cranks or two crank-pins that actuate the twoimpressioncylinders revolve iu the same direction, as the cylinderswould be properly moved if they revolved oppositely, provided they areset quartering. Therefore it will be seen that I have improved two-couple printing-machines so that the same can be runat a very high rate ofspeed, so that' the strain put on the driving mechanism is as near aspossible equal at all times, and that I have provided a webfeedingdevice which has all the advantages .of an intermediate looping system,whereby the web has to be only shifted around one impression-cylinder ata time.

The details and arrangements can be greatly varied by a skilled designerwithout departing from the scope of my invention as expressed in theclaims, and my broad invention 'can be applied as before described.
